SAFETY INSTRUCTIONS

WARNING! Electric shock hazard, rotating fan, and breathing hazard. Unit must be grounded. To reduce risk of electric shock do not expose to water or rain.

Unplug unit prior to service or cleaning.

Do not exceed maximum receptacle load as labeled.
Do not use electrical outlet or power tools that are wet or have been exposed to water.
Inspect the power cord prior to use. If cord or reel is damaged, do not use. Always grasp the plug (not the cord) to unplug.
Only plug the power cord into a matching grounded outlet. Do Not remove third prong.
Do not use with adapter. Do not use extension cord.
Do not use power cord to maneuver the cart.

Use the equipment in conjunction with on-site safety protocols and regulations. Always inspect work area for hazards and be aware of your surroundings.

Confirm work site regulations before use
Always use swivel locks when moving the unit with only one person.
Notify bystanders when using unit in crowded areas.
Keep away from open flame appliances such as gas or propane water heaters, furnaces, etc.
Pressure differences could blow out flame or backdraft combustion products.
Do not operate unit or power tools inside of the unit in the presence of flammable liquids, gasses, or other flammable environments.
Keep retractable enclosure away from open flame.

Prior to use always inspect containment cart for damage. Inspect wheels, brakes, swivels, and casters.
Stay alert and use caution, avoid unnecessary risks at all times.

Do not use while under the influence of drugs, alcohol, or medication.
Wear appropriate attire for work being performed in accordance with company and facility protocols.
Do not wear loose clothing, jewelry, or other items while working inside of the mobile containment cart.

Do not stand on negative air machine assembly.

USAGE AND CARE

This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instructions concerning the use of the appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.

Always follow provided operation manual and instructions.
Inspect and change the pre-filter at regular intervals (weekly, monthly, quarterly), depending on usage and application. More frequent pre-filter changes extend the life of the HEPA filter.

HEPACART recommends the use of PureGreen24 citric acid based cleaner and disinfectant for everyday cleaning of all surfaces. See below for additional cleaning options for more set-in stains.
Window Care: Only use polycarbonate compatible cleaning agents to clean the windows on the HEPACART® or DUSTBUGGY®.
Retractable Enclosure Care : Retractable enclosure is made using healthcare fabrics offering “clean-in-place” convenience. Use neutral soap suds and lukewarm water. Rinse and allow fabric to dry. For hard to clean spots household/vinyl cleansers and/or a soft bristle brush can be used. DO NOT USE HARSH CLENSERS OR SOLVENTS.
Hard Sided Enclosure Care : Do not use abrasive or highly alkaline products, scrape walls with squeegees, razor blades, or other sharp instruments. Do not clean while booth temperature is elevated or when a high percentage of humidity exists.

If scratching should occur, minor abrasions can be removed or minimized by using a mild automotive polish. Examples include Johnson Paste Wax, Mirror Glaze Plastic Polish, Plexus, and Novus Plastic Polish #1 and #2. Always test the chosen product on a small area before overall use.

For units with integral HEPA filtration, the HEPA filter has been tested and certified for one year. The HEPA filter provided with the HEPACART® is a robust, long lasting filter that has been tested and certified at the time of shipment. The HEPA filter, however, is made from a paper media that must be protected if there is chance it will be exposed to moisture.
Before Each Use : Inspect for damage to electrical cord, casters and wheels, retractable enclosure, and negative air machine. Clean up any debris left by the previous job and check negative air machine for a clean pre- filter.
Short term intervals : Inspect pre-filter for accumulated dust and debris that could restrict airflow through the filter. If filter is damaged or visibly dirty, change the prefilter.
Long term intervals : Whenever damage is suspected or at a decrease in airflow, the HEPA filter should be recertified. Testing is recommended annually, at a minimum.

When using in a healthcare application or for remediation: To mitigate the risk of crosscontamination, replace both of the filters and clean the unit thoroughly. Use a damp wipe and vacuum as required. Allow unit to dry before installing new filters.
CHANGING THE FILTERS
Prefilter: Change the pre-filter whenever it shows accumulation of dust and debris. Always change the pre-filter between jobs where dangerous contaminants were present.

Unplug the power cord from line voltage power source.
Remove the (2) two screws from the pre-filter cover on the top of the negative air machine housing.
Remove the pre-filter cover.
Grasp the pre-filter and pull up to remove.
Insert new pre-filter from the top. (minimum MERV 8 pre-filter)
Reposition the cover and re-install (2) screws.

HEPA Filte r: Re-certify HEPA filter on an annual basis and replace if shows signs of damage or reduced airflow. Always change the HEPA filter between jobs where potentially dangerous contaminates are present.

Unplug the power cord from line voltage power source.
Remove the (2) two screws from the pre-filter cover on the top of the negative air machine housing and remove the pre-filter cover.
Release (4) four clasps (2 on each side) of the fan housing.
Remove fan housing.
Remove the dirty HEPA filter from the filter flange.
Carefully install clean HEPA filter. Note direction of airflow and ensure filter media has upstream and downstream gaskets.
Replace fan housing.
